FOAM DYNAMIC FATIGUE TEST BY CONSTANT FORCE POUNDING
The machine according to GB ISO 3385.1989 standard design and manufacturing. Foam compression fatigue testing machine is mainly used for cellular polymeric materials reciprocating compression test, measuring residual deformation rate. It can understand the dynamic fatigue properties of the material. China's automobile industry to meet the standards QCT56-93 "car seat cushioning material performance test method." Japan's auto industry also meet criteria JASOB408-84 and other foreign standards.
